Note: You could mention multiple fish species whatever you want.
For me, my favorite species of fishes are that of the "hammerhead shark", since they're pretty unique looking compared to other shark species, & the evolutionary reason why they evolved with their iconic hammerhead is very interesting.
So yeah, what's your favorite species of fish, & Why? Answer & discuss :)
Also, here's an image of an alternate country I created for fun.
Enjoy :)
